Australia Tanks vs US

[Kern]

More often than not, the aluminium tanks I run across in Oz are more likely to be 11.55lt or 10.35lt WC with a WP of 240 bar (95cft & 85cft respectively), than an 11.25lt WC with a WP of 207 bar (Luxfer Ali 80cft, in Oz).

PS. 3000psi = 207bar

Thanks for asking: I am told "aluminium".

Lots of places call an aluminium 80 cu ft tank a " 12 litre". Egypt for one, ive not yet seen a genuine 12l capacity aluminium tank. The aluminium-80 actual capacity is 11.2l.

Likewise the "15s" are actually 100 cu ft tanks real capacity 13.2l or so

The aluminium tanks operate at a lower working pressure than steel too (207 instead of 232 bar) so in reality an al-80 "12 litre" holds 2318l of gas whereas a genuine steel 12l holds 2784l (some 16% more gas)

Thanks for asking: I am told "aluminium".

OK it'll be an Aluminium 80 then. Buoyant so need extra lead to sink, physically heavier than a same rated steel on land and holds less gas. Welcome to the world of horrible back gas tanks!

The Luxfer aluminium tanks sold into the US are not the same as those sold into Oz, & those sold into Europe are different again.
